Competitive Enzyme Immunoassay by Polyclonal Antibodies Against Organophosphorus Pesticides
<p>Organophosphorus compounds (OPs) comprise one of the major classes of pesticides in use today because they are highly effective and less toxic. Because of their extensive use, there is a need for monitoring OPs in water and vegetables. Gas chromatography (GC) is the usual method for OPs …

Studies on the residue chemistry of some organophosphorus pesticides
… chemistry related to specific studies on two organophosphorus pesticides, viz. Q, Q-diethyl -(K-ethosycarbonyl-8-methylcarbamoylmethyl) phosphorodithioate (common name mecarbam) and 0, G-diethyl S-chloromethyl phosphorodithioate (common name chlormephos). The preparation of a full range of …

STUDIES ON THE ANALYSIS AND THE FATE OF ORGANIC POLLUTANTS IN THE ENVIRONMENT
… thesis deals with the analysis and the fate of pesticides in the environment. In the first part of the thesis, new techniques such as solid-phase extraction, solid-phase microextraction, and electrochemical detection, were studied and applied to the analysis of pesticides and their degradation …

The determination of β-endosulfan and endosulfan sulfate in human serum with dialkylphosphate metabolites as urinary markers using LC-MS/MS electrospray ionization
… agricultural exposure to organochlorine and organophosphorus pesticides using different biological matrices as reference sources. The method that was validated for the quantification of the organochlorine compounds was used to simultaneously determine β-endosulfan [6, 7, 8, 9, 10, 10- …

Organophosphorus Pesticide Exposure Effects on Neurobehavioral Development of Zebrafish and Characterization of Developmental Switch Between Two Cation-chloride Cotransporters (zfnkcc1 and zfkcc2)
<p>Organophosphorus pesticides (OPs) are neuroactive compounds that can affect the development of the nervous system and behavior. Using zebrafish, we compared the effectiveness of three different OPs, chlorpyrifos (CPF), diazinon (DZN) and parathion (PA) on survival, AChE inhibition and larval …

Relationship between urinary levels of organophosphate metabolites and pesticide exposures among rural school boys of the Western Cape
Background: Biomonitoring of pesticides is an objective measure of short-term pesticide exposure as it measures possible exposure in the human body. Current evidence on the relationship between demographic, socio-economic and pesticide exposure risk factors and urinary levels of organophosphate …
